Coordinated Federal Approach to AJF

• Enhance energy security; • Expand domestic energy sources; • Facilitate a diverse, secure, and

reliable fuel supply; • Contribute to price and supply

stability; • Reduce emissions that affect air

quality and global climate; • Generate economic and rural

development; and • Promote social welfare.

Current Two-Phase ASTM Approval Process


Overview and Potential Impact of NJFCP

VisionDevelop an experimental and analytical capability to

facilitate OEM’s evaluation of fuel physical and chemical properties on engine operability and to

streamline ASTM fuels approval process.

IMPACTEarly fuel screening (Tier 2.5), targeted Tier 3 and 4

tests, and increased OEM confidence


Overview and Potential Impact of NJFCP

Tier 2.5 - NJFCP learnings, tests, or screening:• Testing and/or Modeling Route• Determine initial estimate of

maximum percent blend of new fuel with Jet-A

Acceptable Combustor Operability?

Yes

Redesign/Reengineer Fuel Development

Pathway

No

Expensive Certification Tests, which the NJFCP strives to reduce.


NJFCP Executive Summary (testing)Lean Blowout (key certification criteria):• Fuels with distillation, viscosity, and DCN (in particular)

extremes observed to exhibit deleterious performance characteristics.

• For most rigs, Lean Blowout (LBO) was found to correlate with DCN (new result relative to prior studies)• OEMs have identified this as a major NJFCP benefit

Ignition (key certification criteria): • Initial fuel screening at relevant conditions suggests that high

initial distillation temperatures and properties associated with poor spray atomization lead to deleterious performance.

• Initial NJFCP results are consistent with prior experimental studies


NJFCP Executive Summary (modeling)Chemical Kinetics:• Progress achieved connecting fundamental shock tube results

to test rig Lean Blowout results. • Additional in situ hydrocarbon species measurements have

enabled greater model fidelities.• Chemistry model approach for jet fuels validated and

documented

Computational Fluid Dynamics (CFD):• Teams are iterating towards predicting Lean Blowout trends

for selected NJFCP fuels. • CFD combustion model developed into OEM common format

routine (CFR) for alternative jet fuel evaluation in OEM hardware.
